First off, if you do some reading you'll find that the evidence against
Floyd is anything but overwhelming. The fact that his A and B samples tested
the same simply means that the A sample wasn't independently tampered with
and the tests were excuted in a consistent manner, though that does not mean
that the test couldn't be flawed. This is the result one would expect of
such tests. If there had been a difference between the A and B samples, THAT
would have been unexpected.
Contrary to many reports from lazy news sources, Landis did NOT have a high
level of testosterone in his urine. What he had was a high
testosterone-epitestosterone ratio (a.k.a. T-E ratio). "Normal" ratios are
in the 1:1 - 3:1 range, though studies have found significant numbers of men
with natural T-E ratios in the 6:1 range and some as high as 13:1. The WADA
standard for doping is set at 6:1. The UCI used that limit up until this
year, when it dropped its acceptable ratio to 4:1 (I have no idea why).
Although Landis has been reported to have tested with a ratio of 11:1, there
has been no official confirmation of that yet AFAIK.
Testosterone doping is primarily used to build muscle and works over a long
period of time to do so. However, since cycling is not a sport that benefits
from large, bulky muscles, that type of testosterone use would be
counterproductive for a road cyclist (it might benefit a track sprinter).
There is another use for testoterone; it can be used to enhance short-term
recovery. A testosterone patch is place on the scrotum for up to 6 hours and
it will reduce recovery time, supposedly without boosting levels to the
point of exceeding the legal T/E ratio. As yet, there is no evidence that
Landis did this or even knew about the technique.
Urine tests are woefully innacurate, since they don't measure the level of
testosterone in the blood, they only measure how much was excreted by the
body. The UCI knows of the innacuracy, but insists on using urine tests
anyway, probably because they're cheaper than blood tests. To date, every
athlete that has challenged testosterone urine tests has won their case.
There are reports that there was synthetic testosterone in Landis' urine,
which would certainly be problematic for him. OTOH, his levels were legal
after the stages before and after the stage in question (17), which raises
serious questions about the testing. It seems unlikely that an athlete's T-E
ratio could go from legal levels to 11:1 and back to legal levels in 48
hours.
The lab used by the TDF has serious problems of its own. It has been
compromised by the French press (L'Equipe specifically) and information is
constantly leaked by an internal source. It was reviewed independently after
the most recent recent Lance Armstrong debacle and the report lambasted the
lab for inadequate/improper safeguards and procedures, essentially
discrediting it in the L.A. case. Why the TDF still uses the same lab is
anybody's guess, since one would think they'd want to use a lab that doesn't
have a history of problems.
Right now, there are far more questions than answers in this case.
Specifically:
- What is Floyd's natural T/E ratio?
- What was the actual T-E ratio in the tests?
- How much of a difference was there with the results after the previous and
subsequent stages. It makes a big difference if Floyd was 3.9:1 before and
after (just under the legal limit) and 4.1:1 in the tests (just over the
legal limit) vs. being 1:1 before/after and 11:1 in the tests.
- How much could his (legal) medication and self-medication (drinking after
stage 16) have influenced the test results?
- Were the A and B test results consistent (they were both high, but we
don't know if they were the same).
....and for the conspiracy theorists...
- Why does the UCI/TDF rely on urine tests when they KNOW they're
innacurate.
- Why did the UCI drop it's T-E ratio standard to 4:1 THIS year?
- Is it possible that the urine sample container given to Landis was
"spiked" with testosterone and is there any way to determine if that was the
case?
- Exactly how desperate are the French to have someone other than an
American win their beloved race?
It will be interesting to see how this plays out when the actual test data
is revealed and tests are conducted by another lab (assuming they are).
Landis has already been convicted in the press, by his team and by the
organizers of the TDF, but this case is far from over.
